Spark

Spark is a free daily puzzle app where curiosity comes to play.

Each day, Spark explores a single theme, from rebellions and rockets to Pokémon and potatoes, through thoughtful puzzles spanning history, pop culture, science, geography, sports, and more.

With four unique games and new puzzles every day, Spark makes learning part of your routine. Each game offers a different way to explore the day’s theme, whether you’re spotting connections, making comparisons, or reasoning through new facts.

Learn as you play, without pressure, timers, or tests, just the joy of discovery.

Spark’s games include:

This or That: Choose between two options to learn more about the day’s theme
Links: Find the common thread connecting people, places, and ideas
Chrono: Put events in order to see how history really unfolded
Knockout: Uncover surprising comparisons in a series of fun head-to-head matchups


All of Spark’s puzzles are human-crafted by experts, not AI and designed to spark those “aha” moments that make ideas stick. 

Daily themes are explored from multiple angles, with an archive of hundreds of past puzzles so you can revisit previous topics anytime. Along the way, you’ll uncover facts that are fun to learn and even better to share.

From the creators of Elevate and Balance, Spark is part of a collection of mental fitness apps designed to strengthen your mind.
